Metal Forgoing

 Copper smelting began in Catal Huyuk (perhaps the earliest city excavated, found in modern-day Turkey) before the Bronze Age. However, the people in northern Thailand were the fi rst to make bronze (an alloy of tin and copper) around 4000 b.c.e. The fi rst bronze foundry in China developed around 2200 b.c.e. Craftspeople among the Hittites of western Asia perfected iron making for their weapons by 1200 b.c.e.; iron work was also known in central Africa. The Iron Age reached China by 500 b.c.e. Being cheaper to produce than bronze, iron soon found widespread use in war and farming. The Chinese began casting iron a thousand years before Europeans did. At about the same time they began to cast iron the Chinese also began to make steel. Researchers have recently uncovered a Chinese belt buckle made of aluminum, showing that they began to refi ne this metal some 1,500 years before Europeans. In the Andes area gold smelting, used largely for jewelry, developed around 200 b.c.e. After 600 c.e. Western Hemisphere cultures also began to smelt silver and copper but never processed iron or bronze. Rubber was fi rst found among the Chavín culture of the Andes around 1100 b.c.e

Beast and Burden

 The first beasts of burden to be domesticated were the donkey, the buffalo,and the camel, all by 3000 b.c.e. The llama was used in the Andes Mountains in South America.Animal husbandry lagged behind in the Americas because horses died out early in this part of the world and were only reintroduced by Europeans after 1500 c.e. Over the centuries people as far separated as the Celts and Chinese adopted the horse to great advantage. However, at first the horses were mainly used to pull war chariots; later for cavalry, and not commonly for agricultural labor.

SCIENTIFIC AND TECHNOLOGY DEVELOPMENT

 Many ancient cultures were fascinated with the movement of the heavenly bodies because people thought that they exerted infl uence on earthly events. The ancients carefully observed astral rhythms and computed how the seasons fi t this schedule. Sumer, one of the earliest Mesopotamian cities, left behind the fi rst calendar (354 days) by 2700 b.c.e.China had developed a calendar system very similar to the modern one by 1400 b.c.e. In  Central America the Maya developed an amazingly accurate calendar that could predict eclipses and  planetary conjunctions that mirrored the modern way of calculating years, based on a commonly accepted event like the birth of Christ. Dionysius Exiguus (a Christian) invented the current datingsystem in the sixth century.

Indian administrative service ?

 The Indian Administrative Service (IAS) is the administrative arm of the All India Services. Considered the premier civil service of India, the IAS is one of the three arms of the All India Services along with the Indian Police Service and the Indian Forest Service. Members of these three services serve the Government of India as well as the individual states. IAS officers may also be deployed to various public sector undertakings. As with other countries following the parliamentary system of government, the IAS is a part of the permanent bureaucracy of the nation,and is an inseparable part of the executive of the Government of India. As such, the bureaucracy remains politically neutral and guarantees administrative continuity to the ruling party or coalition. Upon confirmation of service, an IAS officer serves a probationary period as a sub-divisional magistrate. Completion of this probation is followed by an executive administrative role in a district as a district magistrate an...
